[Haskell-cafe] Criterion setup/teardown functions?
Is there anything in Criterion that allows for a benchmark to run some code before or after the thing that it's timing? As an example, I'd like to time a bunch of database inserts, but beforehand I want to create the target table, and afterwards I'd like to delete it. I don't really care to have the time spent on the create/delete recorded in the test run's timing, if that's possible to do. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

See the second argument of defaultMainWith http://hackage.haskell.org/packages/archive/criterion/0.6.0.0/doc/html/Criterion-Main.html#v:defaultMainWith. The Criterion monad supports running arbitrary IO actions via liftIO. / Thomas ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Criterion setup/teardown functions?
See the second argument of defaultMainWith http://hackage.haskell.org/packages/archive/criterion/0.6.0.0/doc/html/Criterion-Main.html#v:defaultMainWith. the prep argument is run before the entire suite is run (i.e. once per criterion main invocation); I'm looking for some way to run code before and after each function being benchmarked (and different code around different functions being benchmarked). It looks like criterion is fairly hard-wired to time everything that is done to run a test, so I guess the answer to my question is a straightforward no :) I think I'd have to modify the Benchmarkable typeclass to have a setup and teardown in order to do what I want. Maybe I'll give that a shot. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
